Summary

Actually quite good.

The Good

Since Grand Prix Circuit is your run of the mill racing game, I will only add that it has some good graphics (given that it runs on an XT), simple but effective sound, good controls and reasonbly good level design.

The Bad

Not much really; I would wish for better sound, but then a mere PC speaker is no good. The game was also slightly on the slow side on my friend's old VGA-enabled XT (no kiddin').
